Title: **Innovations of Hidenori Ogata in Semiconductor Technology**
Introduction
Hidenori Ogata, an accomplished inventor based in Gifu, Japan, has made significant contributions to the field of semiconductor technology. With a total of six patents to his name, Ogata's innovations focus on optimizing processes within semiconductor fabrication.
Latest Patents
One of Ogata's notable inventions is the laser anneal method of a semiconductor layer. This innovative approach aims to obtain polycrystalline silicon (p-Si) by irradiating a laser beam onto an amorphous silicon (a-Si) layer. The method involves carefully controlling the energy levels during the annealing process. Specifically, the energy level in the region being irradiated by the laser is designed so that the rear area of the laser scan has a lower energy level compared to the front area or the center. The energy at the front or center area is set to be equal to or above the upper limit that maximizes the grain size of the p-Si produced. By gradually lowering the energy of the laser as it scans the a-Si layer, the semiconductor layer is able to undergo annealing within an optimal energy range during the latter half of the process. This innovative technique enhances the efficiency and effectiveness of semiconductor manufacturing.
